Aviation Edge Autocomplete API returns relevant airports and cities in the database based on the letters requested via the API. This allows your users to pick the airport or city of their choice off the list after typing in the letters when the API is implemented. Basically, the airports the API returns include airports that have the submitted letters anywhere in them. For example, when the letters "ist" are requested, the API returns both "Istanbul Airport" and "Bristol Airport" (among other items). The API is particularly useful for travel agency and flight booking websites, tools, or apps to display the relevant airport and cities as a list for the user to choose from. You may find input parameters, output examples with explanations for each item, filter list, and more in the documentation at http://www.aviation-edge.com/developers Example Fields of Use - Travel agency and flight booking/schedule tracking websites, tools, apps where users are expected to submit a departure or arrival city or airport - Any autocomplete feature related to cities or airports
